MEASURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 724,036, dated March 31 1903. Application filed December 29, 1902. Serial No. 137,085. (No model.)

To all whom it may concern:

Be it known that we, RICHARD ,PARKINSON' and JOHN SOHOLES, subjects of the Kingof Great Britain and Ireland, and residents of Manchester, England, have invented certain new and useful Improvements in Measuring Devices, of which the following is a specification.

This invention refers to scientific drafting or measuring devices chiefly for use in drafting or measuring for the uppers of boots and shoes, although applicable for other and like purposes; and it consists, essentially, of an arrangement of slotted plates or slide-bars and; flexible steeltapesor the like marked with divisions representing measurements of sizes or standards or distances, (or all also off.

means for securely clamping the bars to eachjj .bars) and extending from the boot or shoe sole to a point above the ankle and to the knee or calf. The other bars (hereinafter termed the. girth-bars) lie along the foot and leg center barsat suitable distances apart,

- and each is provided with means forclamping it crosswise and in a definite position.

1 Upon each girth-bar are swivel-loops, also set-screws or clamps.

small slides having swivel-loops, and through such loops the flexible tapes aforesaid are threaded and held after adjustment by small Upon the foot-center bar are two sets of dimensions-one for indicating the size or standard of boot or shoe and the other inches, millimeters, or like scales of measurementand upon each of the other bars and the tapes are dimensions representing inches, millimeters, or like scales of measurement only. I A

To permit of our invention being more clearly understood and carried into practical leg.

[.efiect, we have hereunto appended a sheet of drawings, whereon- I Figure 1 illustrates the complete drafting appliance with the parts as set out in measuringor drafting for the uppers of riding-boots,

and consequently also showing the position of the parts when measuring or drafting for top-boots, boots, and shoes. Figs. 2, 3, and 4 show side or face views of the location-tapes. Fig. 5 shows a section of the plates across the point of connection on line 5 5, Fig. 1. Fig. 6 shows a sectional elevation in part, and Fig. 7 a plan, of a detail and a modification. Fig. 8 shows aboot last and leg from which the measuring or drafting is done and showing the various girths. Figs. 9 and 10 show a further modification.

Referring to Fig. 1, AB C D are a series of thin metal bars,'each slotted and adjustably connected to each other by set-screws E and flat plate-like nuts F, (see Fig. 5,) with or angles to each other, as shown, and constitute the center scale-bar for the leg and center scale and size bar for the foot, respectively. Upon such bars are mounted,further, thin metal and slotted bars H, constituting the girth-bars aforesaid and representing the various girth measures of the boot last and Each of such bars is adjustably connected toone of the center scale-bars by setscrews 1, and when fixed the several bars are designed to represent the toe edge, toe-joint, instep, heel, leg, upper. leg, calf, knee, or

thigh. To one end of each girth-bar is connected a swivel-loop J K, provided with a clamping set-screw L or a cam-like clamp M. (See Figs. 6-and 7.) Through the loops K is threaded a steel or flexible tape N, hereinafter termed the back-location tape, and through the loops J is threaded alike steel-or flexible tape 0, hereinafter termed the bottom-location tape. Upon each girth-bar is alsomounted a slide P, composed, preferably, of two metal plates neatly fitting the bar on either side and held thereto by a set-screw P from below.

- {See Fig. 6.) Upon each slide is mounted a swivelloop Q, provided with set-screw or eccentric clamp, (see Fig. 6,) and, through A disturbance, but with each slide a, by prefersuch loops Q, from toe edge to thigh is threadi ed the steel or flexible tape S, hereinafter termed the top and front location tape. Each of the said tapes S O N is by preference marked in inches, likewise each of the girthbars H and the bars A, B, G, and D. The bar A, however, is alsomarked with the scale corresponding to the usual sizes or standards of boot and shoe measures. With the parts thus assembled (but all the bars free to move) and it is desired to produce the draft of the upper of a riding-boot the bars A B are first set at (or about at) right angles to each other, and the bar B is set along the bar A at a point corresponding to the leg center, the position of which is determined by moving the slide P along the bar A, according to the size of the boot-upper required. The shortest girth-1 bar H is then placed at the extreme end of the bar A, as shown, the angle varying with the; girth of toe, which is afterward determined by the position of the next or toe bar H. With such bar H temporarily fixed by its setscrew I the operator then moves the next bar H untilthe swivel-loop of such bar comes directly opposite the mark on the tape S representing the required measurement from the swivel-loop of the bar H and corresponding to what is termed the top location for the toe, after which such swivel is securely clamped to the tape. Each other swivel-loop Q is then in turn moved to or fro along the tape S until each is the required distance from each other and when each is clamped to the tape S, thus giving the location-points for the top and front of the intended boot upper. The measurements for the top foot 10- cations end at the heel-bar, and those for the front leg locations start at the heel-bar. The locations are then taken along the tapes 0 and N in similar manner, each bar-loop J and K being clamped to the tapes at the proper distance apart, the bottom locations being taken from the toe andthose for the back of the leg from'the heel-bar. Having thus de-' termi ned the locations for both top,front, bottom, and back, the-slides P are adjusted along their respective bars H, according to the girth measurements, which are taken from the swivelloop J K to the loop Q. Each slide is then if desired) clamped to its bar to avoid ence, frictional lit the clamping may not be necessary. The bottom-location tape 0 is then set to the requisite curve representing the spring ofthe foot, which is or may be taken from the boot-last, and the heel-bar is also set to give the required fall of the heel, after which the bars H are all clamped by the manner as'to give a natural form or outline ofa foot or leg, or both, the heel-bar being caused to lie at an angle of forty-five degrees to the-bars A and B. The required draft is then complete and is represented by the outline of the tapes S O N and the girth-barsH,

and it will be seen that the draft of any part of the boot-upper can be obtained therefrom as well as the entire upper.

In arriving at the drafting measurements from the boot-last for the foot part and from the leg itself for the leg part the following rules are observed: For the girth of toe, toejoint, and instep deduct width of bottom of boot-last from girth, add one inch to each result, and divide by. two. Result equals toe, toe-joint, and instep girth measurements on the drafting appliance. For the girth of heel one-half of the boot-last heel-girth equals the drafting heel-girth. For the top and bottom locations of foot add one inch to the boot-last locations. For the leg-girths the draftinggirths equal one-half of the leg-girths. For the front and back leg measurements or locations the measurements are the same as the log, starting from the heel-girth bar. To obtain the size of boot-upper from the bootlast, add three sizes, or one inch, to the boot last size; but this may vary with the fit required.

In lieu of measuring from the boot-last we may, knowing the rules for last-makingfrom foot measurements, take the measurements direct from the foot.

Each location tape and bar is of a length suited to the largest possible draft required, the spare tape ends being coiled within a casing in like fashion to a spring tape-measure or left loose, as desired.

For the uppers of boots and shoes it will be obvious that the bars C and D may be dispensed with and the tapes be shortened accordingly.

Each slide P is cut away, as shown, to allow of the accurate reading of the bar measures and setting of the tapes. The end of tape N is adj ustably secured to tape 0 by clamp N; but it may be secured'to a swivel-loop on the heel-bar H.

For giving a greater accuracy of draft we may employ a greater number of girth-bars. To allow of the adjustment of the heel-bar H without disturbing the adjustment of the bars A B, we may provide a slotted quadrant-plate T, lying between the bars A B or Band H and having projections U, taking loosely into the slot of bar A, and having a small setscrew V, so that after the bars A H are set at right angles (to facilitate which the quadrant-plate may be marked with divisions) the plate and set screw hold .the bars at the proper angle however much the heel-bar H is adjusted, while still allowing the several bars to slide to and fro so long as the screwE is slack.

By our invention it will be seen that we provide facilities for correctly drafting a boot and shoe upper fromthe last without resorting to the old method of drafting on paper with the aid of elaborate scales.

While chiefly for boot-draftingpurposes, the appliance maybe usedfor other drafting purposes, such as producing patterns for dressmaking, model or wood pattern making, and the like.

What we claim is Devices for use in drafting boot and shoe uppers and the like, consisting of a series of thin metal bars all adjustable in relation to each other, and certain of which represent the foot and leg centers, and certain others the girth measures of the boot last and leg, and each marked with inch or other degrees of measurement, and in the case of the footcenter bar also marked with divisions of sizes or standards, also tapes marked with inch or other degrees of measurement and representing the top, front, bottom and
